🚨 Beware of Replay Attacks! I Just Lost My BCH! 😱💸
After 10 years, I finally remembered the password to my Bitcoin wallet. 🎉 Since I held BTC for so long, I also owned its forked coins like Bitcoin Cash ($BCH) and eCash ($XEC). Wanting to consolidate everything, I sent my XEC from Electrum ABC to Binance.
✅ Transaction confirmed. Everything seemed fine…
🚨 But 10 minutes later, my BCH balance was gone! 😨
What Happened? A Classic Replay Attack!
1️⃣ When a blockchain undergoes a hard fork, both chains share the same transaction history up to the split. 📜
2️⃣ If proper replay protection isn’t implemented, a transaction on one chain can be replayed on the other chain. 🔁
3️⃣ My XEC transaction was broadcasted on the BCH network, causing my BCH to be sent to an unintended address!
💔 Binance support couldn’t help because the recipient wasn’t under their control. Luckily, I only lost a buck, but imagine if it were more! 😰
How to Avoid This?
✅ Use split tools: Some wallets allow you to separate addresses for different forks.
✅ Spend small first: Test with a tiny amount before moving large funds.
✅ Manually split coins: Some methods help you spend only on one chain.
💡 If any crypto security pros know a way to recover, let me know! 🛠️
